Everyone has great answers. I would like to add:
- fresh air: tiny bottoms benefit from being in the open air. If you have just changed a diaper consider leaving the new diaper off for an hour or so. It will benefit the little one's delicate skin.
- wrinkles: really deep "wrinkles" of flesh are in that area. I always made sure that I got into the folds of flesh so there were absolutely no damp areas left.
- talc: make sure the baby powder you use is made from corn starch not talc. Corn starch is a natural product and I get the one with Vitamin E and Aloe added. Talc is so fine that it can be inhaled easily by anyone in the immediate area.
- honey: raw honey is great salve. Apply liberally to offending area and diaper up. The honey will stop any infections; draw out excess fluid; soothe the itching, etc.; speed healing; and, is 100% natural.
